Method Detail

compileReadWrite

void compileReadWrite(ICompilationContext ctxt,
                      boolean forReadTarget)
               throws MRuleValidationException

Compiles this accessor to get or set a value. The default target is the context read or write base depending on the "forReadTarget" parameter value.
The contract of the "compileRead(*)" and "compileWrite(*)" methods is globally updated :

• compileRead will always target the read base.
• compileWrite will always target the write base.

Parameters:

forReadTarget - To choose between read or write base for compilation and execution.

Throws:

MRuleValidationException - if validation problem detected.

get

Object get(IExecutionContext ctxt,
           boolean instantiateAll)
    throws MAccessorException

Gets the value of the target. Automatic cast might be done according to specified expected types. If requested, all nested null properties and the final one will be instantiated, if possible. If impossible, an exception is raised.

Throws:

MAccessorException

clone

IReadWriteAccessor clone()

Clones the Accessor.
The general contract is that the clone of a compiled Accessor is still compiled.
