Properties

apiName : Stringreadonly

The name of the API that this proxy corresponds to.

The name of the API that this proxy corresponds to.

The value of this property is the fully qualified name of the API. For example, Button returns Ti.UI.Button.

Indicates if the proxy will bubble an event to its parent. ...

Indicates if the proxy will bubble an event to its parent.

Some proxies (most commonly views) have a relationship to other proxies, often established by the add() method. For example, for a button added to a window, a click event on the button would bubble up to the window. Other common parents are table sections to their rows, table views to their sections, and scrollable views to their views. Set this property to false to disable the bubbling to the proxy's parent.

Default: true

The Window or TabGroup whose Activity lifecycle should be triggered on the proxy.

The Window or TabGroup whose Activity lifecycle should be triggered on the proxy.

If this property is set to a Window or TabGroup, then the corresponding Activity lifecycle event callbacks will also be called on the proxy. Proxies that require the activity lifecycle will need this property set to the appropriate containing Window or TabGroup.

Methods

Adds the specified callback as an event listener for the named event. ...

Adds the specified callback as an event listener for the named event.

Parameters

  • name : String

    Name of the event.

  • callback : Callback<Object>

    Callback function to invoke when the event is fired.

Returns

  • void
Applies the properties to the proxy. ...

Applies the properties to the proxy.

Properties are supplied as a dictionary. Each key-value pair in the object is applied to the proxy such that myproxy[key] = value.

Returns

Closes this stream. ...

Closes this stream.

Throws an exception on error.

Returns

  • void
Fires a synthesized event to any registered listeners. ...

Fires a synthesized event to any registered listeners.

Parameters

  • name : String

    Name of the event.

  • event : Dictionary

    A dictionary of keys and values to add to the Titanium.Event object sent to the listeners.

Returns

  • void
Gets the value of the apiName property. ...

Returns

Indicates whether this stream is readable. ...

Indicates whether this stream is readable.

Returns

  • Boolean

    True if stream is readable, false otherwise.

Indicates whether this stream is writable. ...

Indicates whether this stream is writable.

Returns

  • Boolean

    True if stream is writable, false otherwise.

( buffer, [offset], [length] ) : Number
Reads data from this stream into a buffer. ...

Reads data from this stream into a buffer.

If offset and length are specified, data is written into the buffer starting at position offset. Data is read from this stream until one of the following occurs:

  • the end of this stream is reached
  • the end of the buffer is reached
  • a total of length bytes have been read from the stream

If offset and length are omitted, data is written starting at the beginning of the buffer.

Returns the number of bytes read, or -1 if the end of stream was reached before any data was read.

Throws an exception on error. For example, if the offset value is past the last byte of buffer.

This method is synchronous. To perform an asynchronous read on an IOStream, use Titanium.Stream.read.

Parameters

  • buffer : Titanium.Buffer

    Buffer to read stream data into.

  • offset : Number (optional)

    Offset into the buffer to start writing stream data. If specified, length must also be specified.

  • length : Number (optional)

    Maximum number of bytes to read. If specified, offset must also be specified.

Returns

  • Number

    Number of bytes read.

Removes the specified callback as an event listener for the named event. ...

Removes the specified callback as an event listener for the named event.

Multiple listeners can be registered for the same event, so the callback parameter is used to determine which listener to remove.

When adding a listener, you must save a reference to the callback function in order to remove the listener later:

var listener = function() { Ti.API.info("Event listener called."); }
window.addEventListener('click', listener);

To remove the listener, pass in a reference to the callback function:

window.removeEventListener('click', listener);

Parameters

  • name : String

    Name of the event.

  • callback : Callback<Object>

    Callback function to remove. Must be the same function passed to addEventListener.

Returns

  • void
Sets the value of the bubbleParent property. ...

Sets the value of the bubbleParent property.

  • 3.0.0
  • 3.0.0
  • 3.0.0

Parameters

  • bubbleParent : Boolean

    New value for the property.

Returns

  • void
Sets the value of the lifecycleContainer property. ...

Sets the value of the lifecycleContainer property.

  • 3.6.0

Parameters

Returns

  • void
( buffer, [offset], [length] ) : Number
Writes data from a buffer to this stream. ...

Writes data from a buffer to this stream.

If offset and length are specified, data is read from the buffer starting at offset. Bytes are read from the buffer and written to the stream until:

  • the end of the buffer is reached
  • length bytes have been written
  • the stream returns an error

If offset and length are omitted, all of the data in the buffer is written to this stream.

Returns the number of bytes actually written.

Throws an exception if an error is encountered.

Parameters

  • buffer : Titanium.Buffer

    Buffer to write to this stream.

  • offset : Number (optional)

    Offset in the buffer of the first byte to write to the stream. If specified, length must also be specified.

  • length : Number (optional)

    Maximum number of bytes to write to the stream. If specified, offset must also be specified.

Returns

  • Number

    Number of bytes written.
