Constructor Details

DataOutputStream

public DataOutputStream(MemorySegment address)

Create a DataOutputStream proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

DataOutputStream

public DataOutputStream(OutputStream baseStream)

Creates a new data output stream for baseStream.

Parameters:

baseStream - a GOutputStream.

DataOutputStream

public DataOutputStream()

Creates a new DataOutputStream.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the DataOutputStream class

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected DataOutputStream asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class FilterOutputStream

getByteOrder

public DataStreamByteOrder getByteOrder()

Gets the byte order for the stream.

Returns:

the GDataStreamByteOrder for the stream.

putByte

public boolean putByte(byte data,
 @Nullable Cancellable cancellable)
                throws GErrorException

Puts a byte into the output stream.

Parameters:

data - a guchar.

cancellable - optional GCancellable object, null to ignore.

Returns:

true if data was successfully added to the stream.

Throws:

GErrorException - see GError

putInt16

public boolean putInt16(short data,
 @Nullable Cancellable cancellable)
                 throws GErrorException

Puts a signed 16-bit integer into the output stream.

Parameters:

data - a gint16.

cancellable - optional GCancellable object, null to ignore.

Returns:

true if data was successfully added to the stream.

Throws:

GErrorException - see GError

putInt32

public boolean putInt32(int data,
 @Nullable Cancellable cancellable)
                 throws GErrorException

Puts a signed 32-bit integer into the output stream.

Parameters:

data - a gint32.

cancellable - optional GCancellable object, null to ignore.

Returns:

true if data was successfully added to the stream.

Throws:

GErrorException - see GError

putInt64

public boolean putInt64(long data,
 @Nullable Cancellable cancellable)
                 throws GErrorException

Puts a signed 64-bit integer into the stream.

Parameters:

data - a gint64.

cancellable - optional GCancellable object, null to ignore.

Returns:

true if data was successfully added to the stream.

Throws:

GErrorException - see GError

putString

public boolean putString(String str,
 @Nullable Cancellable cancellable)
                  throws GErrorException

Puts a string into the output stream.

Parameters:

str - a string.

cancellable - optional GCancellable object, null to ignore.

Returns:

true if string was successfully added to the stream.

Throws:

GErrorException - see GError

putUint16

public boolean putUint16(short data,
 @Nullable Cancellable cancellable)
                  throws GErrorException

 @Nullable Cancellable cancellable)
                  throws GErrorException

Puts an unsigned 32-bit integer into the stream.

Parameters:

data - a guint32.

cancellable - optional GCancellable object, null to ignore.
