Method Detail

compile

public boolean compile(ITypeConverter converter,
                       ICompilationContext ctx,
                       ICompilationResultWriter messages)

Description copied from interface: IExprNode

Allow to compile the given expression with the associated and . All messages will be stored into the at the end of the performed compilation.

Parameters:

converter - Interface for conversion types

ctx - Interface for compilation context

messages - Represent where the messages compilation will be stored

Returns:

getType

public java.lang.Class<?> getType()

Description copied from interface: IExpression

Returns the expression type

getGenericType

public java.lang.reflect.Type getGenericType()

Description copied from interface: IExpression

Returns the expression generic type

invoke

public java.lang.Object invoke(IEvaluationContext context)
                        throws java.lang.Exception

Description copied from interface: IExpression

Evaluates the expression.

Throws:

java.lang.Exception

isStaticValue

public boolean isStaticValue()

Description copied from interface: IExpression

Returns true if the expression has a static value (i.e. that does not depend on any evaluation context). In such a case, the invoke(...) method may be called with a null evaluation context.

Returns:

boolean

appendExpressionString

protected void appendExpressionString(java.lang.StringBuilder b)

Description copied from class: AstNode

Recursive method to build an expression string form.

Specified by:

appendExpressionString in class AstNode

appendValuePattern

protected void appendValuePattern(java.lang.StringBuilder builder)

Description copied from class: AstNode

Recursive method to build the returned values regular expression. This is used for advanced validation.

Specified by:

appendValuePattern in class AstNode
