Method Detail

copyFrom

public void copyFrom(com.sun.jna.Pointer buffer)

Description copied from class: Value

Reads all elements of that value from a piece of memory pointed to by buffer. You have to make sure, that the size of this buffer is at least Value.getSerializedSize().

Specified by:

copyFrom in class Value

Parameters:

buffer - a pointer to free memory

copyTo

public void copyTo(com.sun.jna.Pointer buffer)

Description copied from class: Value

Writes all elements of that value to a piece of memory pointed to by buffer. You have to make sure, that the size of this buffer is at least Value.getSerializedSize().

Specified by:

copyTo in class Value

Parameters:

buffer - a pointer to free memory

getE1

public double getE1()

getE2

public double getE2()

parseFrom

public boolean parseFrom(java.util.Scanner sc)

Description copied from class: Value

Parses new content of that value from the given Scanner.

Specified by:

parseFrom in class Value

Parameters:

sc - a Scanner to parse the data from

Returns:

true if on success, false otherwise.

printTo

public java.io.PrintStream printTo(java.io.PrintStream ps)

Description copied from class: Value

Prints all elements of that value to a stream in a human-readable format.

Specified by:

printTo in class Value

Parameters:

ps - a stream to print all elements to

setE1

public void setE1(double e1)

setE2

public void setE2(double e2)

set

public void set(double e1,
                double e2)

getSharedMemory

public com.sun.jna.Memory getSharedMemory()

Description copied from class: Value

Returns a pointer to a piece of memory, that provides space for at least Value.getSerializedSize() bytes and can be directly used in conjunction with Value.copyTo(Pointer) and Value.copyFrom(Pointer).

For the sake of efficiency the provided memory may be some sort of shared memory, which can be used temporarily, to transfer data somewhere, e.g. to native code. Please note that the usage of this buffer in multi-threaded code has to be synchronized.

Specified by:

getSharedMemory in class Value

Returns:

a pointer to some shared memory, which is large enough to serialize this object to

getSerializedSize

public int getSerializedSize()

Description copied from class: Value

Returns the size in bytes of this object when serialized.

Specified by:

getSerializedSize in class Value

Returns:

the size in bytes

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object
