ELContextImpl

public ELContextImpl(ELResolver resolver)

Constructs a new ELContext associated with the given ELResolver.

方法详细信息

getELResolver

public ELResolver getELResolver()

从类 ELContext 复制的描述

Retrieves the ELResolver associated with this context.

The ELContext maintains a reference to the ELResolver that will be consulted to resolve variables and properties during an expression evaluation. This method retrieves the reference to the resolver.

Once an ELContext is constructed, the reference to the ELResolver associated with the context cannot be changed.

指定者：

类 ELContext 中的 getELResolver

返回：

The resolver to be consulted for variable and property resolution during expression evaluation.

setFunctionMapper

public void setFunctionMapper(FunctionMapper fnMapper)

getFunctionMapper

public FunctionMapper getFunctionMapper()

从类 ELContext 复制的描述

Retrieves the FunctionMapper associated with this ELContext.

指定者：

类 ELContext 中的 getFunctionMapper

返回：

The function mapper to be consulted for the resolution of EL functions.

setVariableMapper

public void setVariableMapper(VariableMapper varMapper)

getVariableMapper

public VariableMapper getVariableMapper()

从类 ELContext 复制的描述

Retrieves the VariableMapper associated with this ELContext.

指定者：

类 ELContext 中的 getVariableMapper

返回：

The variable mapper to be consulted for the resolution of EL variables.
