MapVariableResolver

public MapVariableResolver(java.util.Map<java.lang.String,java.lang.Object> variableMap,
                           java.lang.String name)

MapVariableResolver

public MapVariableResolver(java.util.Map variableMap,
                           java.lang.String name,
                           java.lang.Class knownType)

Method Detail

setName

public void setName(java.lang.String name)

setStaticType

public void setStaticType(java.lang.Class knownType)

Specified by:

setStaticType in interface VariableResolver

setVariableMap

public void setVariableMap(java.util.Map variableMap)

getName

public java.lang.String getName()

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

This should return the type of the variable. However, this is not completely necessary, and is particularily only of benefit to systems that require use of MVEL's strict typing facilities. In most cases, this implementation can simply return: Object.class

Specified by:

getType in interface VariableResolver

Returns:

A Class instance representing the type of the target variable.

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.

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.

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.
