Constructor Detail

ArrayLiteral

protected ArrayLiteral(QueryExpression qs)

Constructor

Parameters:

qs - The query statement

ArrayLiteral

public ArrayLiteral(QueryExpression qs,
                    ScalarExpression[] expr)

Constructor

Parameters:

qs - The query statement

expr - the array of expressions

ArrayLiteral

public ArrayLiteral(QueryExpression qs,
                    JavaTypeMapping mapping,
                    java.lang.Object literal)

Constructor

Parameters:

qs - The query statement

mapping - the JavaTypeMapping

literal - the array value

Method Detail

getValue

public java.lang.Object getValue()

Description copied from interface: Literal

Accessor to the literal value

Specified by:

getValue in interface Literal

Returns:

the value of the literal

setRawValue

public void setRawValue(java.lang.Object val)

Method to save a "raw" value that this literal represents. This value differs from the literal value since that is of the same type as this literal.

Specified by:

setRawValue in interface Literal

Parameters:

val - The raw value

getRawValue

public java.lang.Object getRawValue()

Accessor for the "raw" value that this literal represents. This value differs from the literal value since that is of the same type as this literal.

Specified by:

getRawValue in interface Literal

Returns:

The raw value
