Class InputParameter

java.lang.Object

com.goldencode.p2j.util.InputParameter

public class InputParameter
extends java.lang.Object

Defines APIs emitted to preserve the conversion-time type of an expression, and allow the runtime to check if the evaluated value of this expression matches the conversion-time type or not.

For OO method calls, this ensures that the proper overloaded method is resolved, as this requires the conversion-time type, for both direct and dynamic calls.

Method Detail

arg

public static Resolvable arg(java.lang.Class<? extends BaseDataType> type,
                             BaseDataType value)

Cast the runtime value to the specified type. If the assignment fails, then the next top-level block will not be executed, and instead argument failure errors are shown/thrown.

This API is emitted when the target top-level block is a direct Java call for a legacy OO method.

Parameters:

type - The conversion-time type of the expression.

value - The runtime value of the argument.

Returns:

The value converted to the conversion-time type.

function

public static <T extends BaseDataType> T function(java.lang.Class<T> type,
                                                  BaseDataType value)

Cast the runtime value to the specified type. If the assignment fails, then the next top-level block will not be executed, and instead argument failure errors are shown/thrown.

This API is emitted when the target top-level block is a function.

Parameters:

type - The conversion-time type of the expression.

value - The runtime value of the argument.

Returns:

The value converted to the conversion-time type.

procedure

public static <T extends BaseDataType> T procedure(java.lang.Class<T> type,
                                                   BaseDataType value)

Cast the runtime value to the specified type. If the assignment fails, then the next top-level block will not be executed, and instead argument failure errors are shown/thrown.

This API is emitted when the target top-level block is from a RUN statement.

Parameters:

type - The conversion-time type of the expression.

value - The runtime value of the argument.

Returns:

The value converted to the conversion-time type.

property

public static <T extends BaseDataType> T property(java.lang.Class<T> type,
                                                  BaseDataType value)

Cast the runtime value to the specified type. If the assignment fails, then the next top-level block will not be executed, and instead argument failure errors are shown/thrown.

This API is emitted when the target top-level block is a property setter.

Parameters:

type - The conversion-time type of the expression.

value - The runtime value of the argument.

Returns:

The value converted to the conversion-time type.

cast

public static <T extends BaseDataType> T cast(java.lang.Class<T> type,
                                              BaseDataType value)

Cast the runtime value to the specified type. If the assignment fails, then the next top-level block will not be executed, and instead argument failure errors are shown/thrown.

Parameters:

type - The conversion-time type of the expression.

value - The runtime value of the argument.

Returns:

The value converted to the conversion-time type.

cast

private static <T extends BaseDataType> T cast(java.lang.Class<T> type,
                                               boolean error,
                                               BaseDataType value,
                                               java.lang.String errMsg,
                                               int errNum)

Cast the runtime value to the specified type. If the assignment fails, then the next top-level block will not be executed, and instead argument failure errors are shown/thrown.

Parameters:

type - The conversion-time type of the expression.

error - Flag indicating if an ERROR condition needs to be raised.

value - The runtime value of the argument.

errMsg - The error message to add in case of failure.

errNum - The error number to add in case of failure.

Returns:

The value converted to the conversion-time type.
