Method Detail
-
setName
public void setName(java.lang.String name)
-
setStaticType
public void setStaticType(java.lang.Class knownType)
- Specified by:
setStaticType
in interfaceVariableResolver
-
getName
public java.lang.String getName()
Description copied from interface:VariableResolver
Returns the name of external variable.- Specified by:
getName
in interfaceVariableResolver
- 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 interfaceVariableResolver
- 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 interfaceVariableResolver
- 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 interfaceVariableResolver
- 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 interfaceVariableResolver
- Returns:
- Bitset of special flags.
