Method Detail

bytesToString

protected java.lang.String bytesToString(byte[] bytes)

stringToBytes

protected byte[] stringToBytes(java.lang.String value)

clone

public java.lang.Object clone()

Specified by:

clone in class Parameter

getStrLen

protected int getStrLen(DataBuffer dataBuffer,
                        int startOffset)

getMaxLength

public int getMaxLength()

Returns the maximum length of a string. In certain (mostly Asian) encodings, some characters are represented by more than one byte even if the charLength is 1. In these cases ANSI string may not be able to hold getMaxLength() characters. Creating a new AnsiString object with the string as a parameter or using WideString eliminates this problem.

setValue

public final void setValue(java.lang.String[] value)

toBytes

public final byte[] toBytes(java.lang.String[] value)

getValue

public final java.lang.String[] getValue()

getCharLength

protected int getCharLength()

Returns the character length in bytes.

getAlignedLength

protected int getAlignedLength()

Description copied from class: Parameter

Returns a parameter length in bytes aligned to default alignment.

Overrides:

getAlignedLength in class Parameter

asReturnValue

protected Parameter asReturnValue()

Description copied from class: Parameter

Returns a parameter that represents this one as a return value. Implementors may use this as a convenience shortcut for users when implementing such objects as strings or arrays to allow users to specify an object as a return value instead of requiring a pointer to it. For general use the default implementation should suffice.

Overrides:

asReturnValue in class Parameter

Returns:

this

write

public void write(DataBuffer stackBuffer,
                  int offset,
                  boolean invokedByCallback)
           throws MemoryAccessViolationException

Description copied from class: Parameter

Writes this parameter to a specified data source.

Specified by:

write in class Parameter

Throws:

MemoryAccessViolationException

read

public void read(DataBuffer stackBuffer,
                 int offset,
                 boolean invokedByCallback)
          throws MemoryAccessViolationException

Description copied from class: Parameter

Reads this parameter from a specified data source.

Specified by:

read in class Parameter

Throws:

MemoryAccessViolationException

getDebugInfo

public java.lang.String getDebugInfo()

Description copied from class: Parameter

Return debug info for JNIWrapper parameter.

Specified by:

getDebugInfo in class Parameter

Returns:

debug info

equals

public boolean equals(java.lang.Object obj)

Description copied from class: Parameter

Compares this Parameter object to a given object. Two Parameter objects are considered equal if their byte representations are equal and they are of the same type. Subclasses may override this method as appropriate.

Overrides:

equals in class Parameter

Parameters:

obj - a value to compare this object to.

Returns:

true if two objects are equal.

hashCode

public int hashCode()

Overrides:

hashCode in class Parameter

getLength

public int getLength()

Description copied from class: Parameter

Returns the length of the parameter in memory. This method is similar to C sizeof() operator.

Specified by:

getLength in class Parameter
