VariableResolver
public interface VariableResolver (Code)
A variable resolver is responsible for physically accessing a variable, for either read or write. VariableResolver's are obtained via a org.mvel.integration.VariableResolverFactory .

Method Summary
public int getFlags()
     Returns the bitset of special variable flags.
public String getName()
     Returns the name of external variable.
public Class getType()
     This should return the type of the variable.
public Object getValue()
     Returns the physical target value of the variable.
public void setStaticType(Class type)

public void setValue(Object value)
     Sets the value of the physical target value.

Method Detail
getFlags
public int getFlags()(Code)
Returns the bitset of special variable flags. Internal use only. This should just return 0 in custom implentations. Bitset of special flags.

getName
public String getName()(Code)
Returns the name of external variable. A string representing the variable name.
