AstBracket

public AstBracket(int position,
                  AstNode base,
                  AstNode property,
                  boolean lvalue)

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:

invoke

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

Description copied from interface: IExpression

Evaluates the expression.

Throws:

java.lang.Exception

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

set

public void set(IEvaluationContext iContext,
                java.lang.Object iValue)
         throws ExpressionEvaluationException

Description copied from interface: IExpression

Assigns a value to this expression (if no read only)

Throws:

ExpressionEvaluationException

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

isReadOnly

public boolean isReadOnly()

Description copied from interface: IExpression

Returns true if the expression cannot be set

Returns:

boolean

appendExpressionString

protected void appendExpressionString(java.lang.StringBuilder builder)

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
