public class BindableCpoWhere
extends Node

Constructor Details

BindableCpoWhere

public BindableCpoWhere(Logical logical,
 String attr,
 Comparison comp,
 T value)

Creates a leaf where clause comparing the named attribute to a literal value, joined to a subsequent clause (if any) by the given logical operator.

Type Parameters:

T - the type of the comparison value

Parameters:

logical - the logical operator joining this clause to the next one added

attr - the name of the bean attribute to compare

comp - the comparison operator to apply

value - the value to compare the attribute against

BindableCpoWhere

public BindableCpoWhere(Logical logical,
 String attr,
 Comparison comp,
 T value,
 boolean not)

Creates a leaf where clause comparing the named attribute to a literal value, optionally negated, joined to a subsequent clause (if any) by the given logical operator.

Type Parameters:

T - the type of the comparison value

Parameters:

logical - the logical operator joining this clause to the next one added

attr - the name of the bean attribute to compare

comp - the comparison operator to apply

value - the value to compare the attribute against

not - true to negate the comparison, false otherwise

BindableCpoWhere

public BindableCpoWhere()

Creates an empty where clause with no comparison, attribute, or value set.

Method Details

setComparison

public void setComparison(Comparison comparison)

Sets the Comparison operator (e.g. equals, greater-than) used to compare the attribute against the value or right-hand attribute.

Specified by:

setComparison in interface CpoWhere

Parameters:

comparison - the comparison operator for this where clause

getComparison

public Comparison getComparison()

Gets the Comparison operator used to compare the attribute against the value or right-hand attribute.

Specified by:

getComparison in interface CpoWhere

Returns:

the comparison operator for this where clause

setLogical

public void setLogical(Logical logical)

Sets the Logical operator (e.g. AND, OR) used to join this where clause with the next one added via CpoWhere.addWhere(CpoWhere).

Specified by:

setLogical in interface CpoWhere

Parameters:

logical - the logical operator joining this clause to the next

getLogical

public Logical getLogical()

Gets the Logical operator used to join this where clause with the next one added via CpoWhere.addWhere(CpoWhere).

Specified by:

getLogical in interface CpoWhere

Returns:

the logical operator joining this clause to the next

setAttribute

public void setAttribute(String s)

Sets the name of the bean attribute on the left-hand side of the comparison.

Specified by:

setAttribute in interface CpoWhere

Parameters:

s - the attribute name

getAttribute

public String getAttribute()

Gets the name of the bean attribute on the left-hand side of the comparison.

Specified by:

getAttribute in interface CpoWhere

Returns:

the attribute name

setRightAttribute

public void setRightAttribute(String s)

Sets the name of the bean attribute to compare against, when comparing two attributes rather than an attribute and a literal value.

Specified by:

setRightAttribute in interface CpoWhere

Parameters:

s - the right-hand attribute name

getRightAttribute

public String getRightAttribute()

Gets the name of the bean attribute to compare against, when comparing two attributes rather than an attribute and a literal value.

Specified by:

getRightAttribute in interface CpoWhere

Returns:

the right-hand attribute name

setValue

public void setValue(Object s)

Sets the literal value to compare the attribute against.

Specified by:

setValue in interface CpoWhere

Parameters:

s - the comparison value

getValue

public Object getValue()

Gets the literal value the attribute is compared against.

Specified by:

getValue in interface CpoWhere

Returns:

the comparison value

setStaticValue

public void setStaticValue(String staticValue)

Sets a literal, unescaped value to use in place of a bound comparison value, inserted directly into the native expression.

Specified by:

setStaticValue in interface CpoWhere

Parameters:

staticValue - the static (literal) value text

getStaticValue

public String getStaticValue()

Gets the literal, unescaped value used in place of a bound comparison value.

Specified by:

getStaticValue in interface CpoWhere

Returns:

the static (literal) value text

getNot

public boolean getNot()

Gets whether this where clause's comparison result is negated.

Specified by:

getNot in interface CpoWhere

Returns:

`true` if the comparison is negated (NOT), `false` otherwise

setNot

public void setNot(boolean b)

Sets whether this where clause's comparison result should be negated.

Specified by:

setNot in interface CpoWhere

Parameters:

b - `true` to negate the comparison (NOT), `false` otherwise

toString

public String toString(CpoClass cpoClass)

Builds the native (SQL/CQL) fragment for this where clause against the given class's attribute-to-column mapping. Unlike Object.toString(), this resolves attribute names to datastore column names and does not require the class to declare the attribute (unresolved names are used verbatim, e.g. as raw column names).

Parameters:

cpoClass - the class metadata used to resolve attributes to datastore columns

Returns:

the native expression fragment for this clause

addWhere

public void addWhere(CpoWhere cw)
              throws CpoException

Chains another where clause onto this one, joined by this instance's Logical operator, turning this instance into a branch node.

The added clause must itself be a Node (all built-in CpoWhere implementations are); it is attached as a child node of this instance.

Specified by:

addWhere in interface CpoWhere

Parameters:

cw - the where clause to add

Throws:

CpoException - if the where clause cannot be added

setAttributeFunction

public void setAttributeFunction(String s)

Specified by:

setAttributeFunction in interface CpoWhere

Parameters:

s - the function expression to apply to the attribute

getAttributeFunction

public String getAttributeFunction()

Gets the native datastore function applied to the left-hand attribute before comparison.
