Description copied from interface: VariableResolver

Returns the name of external variable.

Specified by:

getName in interface VariableResolver

Returns:

A string representing the variable name.

getType

public java.lang.Class getType()

Description copied from interface: VariableResolver

Specified by:

getType in interface VariableResolver

Returns:

A Class instance representing the type of the target variable.

setStaticType

public void setStaticType(java.lang.Class type)

Specified by:

setStaticType in interface VariableResolver

getFlags

public int getFlags()

Description copied from interface: VariableResolver

Returns the bitset of special variable flags. Internal use only. This should just return 0 in custom implentations.

Specified by:

getFlags in interface VariableResolver

Returns:

Bitset of special flags.

getValue

public java.lang.Object getValue()

Description copied from interface: VariableResolver

Returns the physical target value of the variable.

Specified by:

getValue in interface VariableResolver

Returns:

The actual variable value.

setValue

public void setValue(java.lang.Object value)

Description copied from interface: VariableResolver

Sets the value of the physical target value.

Specified by:

setValue in interface VariableResolver

Parameters:

value - The new value.
