Method Details

copy

public FileEntity copy()

Description copied from class: BasicHttpEntity

Creates a builder for this class initialized with the contents of this bean.

Allows you to create a modifiable copy of this bean.

Overrides:

copy in class BasicHttpEntity

Returns:

A new builder bean.

asString

public String asString()
                throws IOException

Description copied from class: BasicHttpEntity

Converts the contents of this entity as a string.

Note that this may exhaust the content on non-repeatable, non-cached entities.

Overrides:

asString in class BasicHttpEntity

Returns:

The contents of this entity as a string.

Throws:

IOException - If a problem occurred while trying to read the content.

asBytes

public byte[] asBytes()
               throws IOException

Description copied from class: BasicHttpEntity

Converts the contents of this entity as a byte array.

Note that this may exhaust the content on non-repeatable, non-cached entities.

Overrides:

asBytes in class BasicHttpEntity

Returns:

The contents of this entity as a byte array.

Throws:

IOException - If a problem occurred while trying to read the content.

isRepeatable

public boolean isRepeatable()

Specified by:

isRepeatable in interface HttpEntity

Overrides:

isRepeatable in class BasicHttpEntity

getContentLength

public long getContentLength()

Specified by:

getContentLength in interface HttpEntity

Overrides:

getContentLength in class BasicHttpEntity

getContent

public InputStream getContent()
                       throws IOException

Specified by:

getContent in interface HttpEntity

Overrides:

getContent in class BasicHttpEntity

Throws:

IOException

writeTo

public void writeTo(OutputStream out)
             throws IOException

Specified by:

writeTo in interface HttpEntity

Overrides:

writeTo in class BasicHttpEntity

Throws:

IOException

setCached

public FileEntity setCached()
                     throws IOException

Description copied from class: BasicHttpEntity

Specifies that the contents of this resource should be cached into an internal byte array so that it can be read multiple times.

Overrides:

setCached in class BasicHttpEntity

Returns:

This object.

Throws:

IOException - If entity could not be read into memory.

setCharset

public FileEntity setCharset(Charset value)

Description copied from class: BasicHttpEntity

Specifies the charset to use when converting to and from stream-based resources.

Overrides:

setCharset in class BasicHttpEntity

Parameters:

value - The new value. If null, UTF-8 is assumed.

Returns:

This object.

setChunked

public FileEntity setChunked()

Description copied from class: BasicHttpEntity

Sets the 'chunked' flag value to true.

Notes:

• If the HttpEntity.getContentLength() method returns a negative value, the HttpClient code will always use chunked encoding.

Overrides:

setChunked in class BasicHttpEntity

Returns:

This object.

setChunked

public FileEntity setChunked(boolean value)

Description copied from class: BasicHttpEntity

Sets the 'chunked' flag value.

setChunked in class BasicHttpEntity

Parameters:

value - The new value for this flag.

Returns:

This object.
