Constructor Detail

StringLiteral

public StringLiteral(StringValue value,
             Container container)

Create a StringLiteral that wraps a StringValue

Parameters:

value - the StringValue

container - the container in the expression tree. Should not be null. Saxon does not reject a null value for the container, but it may cause subsequent failures if a container is not supplied at some stage.

StringLiteral

public StringLiteral(CharSequence value,
             Container container)

Create a StringLiteral that wraps any CharSequence (including, of course, a String)

Parameters:

value - the CharSequence to be wrapped

container - the container in the expression tree. Should not be null. Saxon does not reject a null value for the container, but it may cause subsequent failures if a container is not supplied at some stage.

Method Detail

getStringValue

public String getStringValue()

Get the string represented by this StringLiteral

Returns:

the underlying string

copy

public Expression copy()

Description copied from class: Literal

Copy an expression. This makes a deep copy.

Overrides:

copy in class Literal

Returns:

a copy of the original literal. Note that the underlying value is not copied; the code relies on the caller treating the underlying value as immutable.
