Method Detail

methodBinding

public static El methodBinding(String retrieve,
                               String submit)

Create a new EL Method binding using distinct expressions to submit and retrieve values. The method intended for use in submission must accept a single parameter of the expected type.

retrievalMethod

public static El retrievalMethod(String expression)

Create a new EL Method binding to retrieve values. The method must return a value of the expected type.

retrievalMethod

public static El retrievalMethod(Method method)

Create a new EL Method binding to retrieve values. This method allows the caller to supply El.ElMethod instance to refer to the method that should be invoked.

retrievalMethod

public static El retrievalMethod(String expression,
                                 Class<? extends Converter<?>> converterType)

Create a new EL Method binding to retrieve values. The method must return a value of the expected type. Use the given Converter when retrieving any values.

submissionMethod

public static El submissionMethod(String expression)

Create a new EL Method binding to submit values. The method must accept a single parameter of the expected type.

submissionMethod

public static El submissionMethod(String expression,
                                  Class<? extends Converter<?>> converterType)

Create a new EL Method binding to submit values. The method must accept a single parameter of the expected type. Use the given Converter before submitting any values.

submissionMethod

public static El submissionMethod(String expression,
                                  Class<? extends Converter<?>> converterType,
                                  Class<? extends Validator<?>> validatorType)

Create a new EL Method binding to submit values. The method must accept a single parameter of the expected type. Use the given Validator before attempting to submit any values. Use the given Converter before submitting any values.

property

public static El property(String expression)

Create a new EL Value binding using a single expression to submit and retrieve values. The specified property must either be public, or have a publicly defined getter/setter.

property

public static El property(Field field)

Create a new EL Value binding using a single expression to submit and retrieve values. The specified property must either be public, or have a publicly defined getter/setter. Instead of an EL expression this method expects a Field argument. The EL expression will be automatically created at runtime.

property

public static El property(String expression,
                          Class<? extends Converter<?>> type)

Create a new EL Value binding using a single expression to submit and retrieve values. The specified property must either be public, or have a publicly defined getter/setter. Use the given Converter before submitting any values.

property

public static El property(String expression,
                          Class<? extends Converter<?>> converterType,
                          Class<? extends Validator<?>> validatorType)

Create a new EL Value binding using a single expression to submit and retrieve values. The specified property must either be public, or have a publicly defined getter/setter. Use the given Validator before attempting to submit any values. Use the given Converter when submitting any values.
