StringEntity

public StringEntity(String string,
 ContentType contentType)
             throws UnsupportedCharsetException

Creates a StringEntity with the specified content and content type.

Parameters:

string - content to be used. Not null.

contentType - content type to be used. May be null, in which case the default MIME type ContentType.TEXT_PLAIN is assumed.

Throws:

IllegalArgumentException - if the string parameter is null

UnsupportedCharsetException - Thrown when the named charset is not available in this instance of the Java virtual machine

Since:

4.2

StringEntity

@Deprecated
public StringEntity(String string,
 String mimeType,
 String charset)
             throws UnsupportedEncodingException

Deprecated.

(4.1.3) use StringEntity(String, ContentType)

Creates a StringEntity with the specified content, MIME type and charset

Parameters:

string - content to be used. Not null.

mimeType - MIME type to be used. May be null, in which case the default is HTTP.PLAIN_TEXT_TYPE i.e. "text/plain"

charset - character set to be used. May be null, in which case the default is HTTP.DEF_CONTENT_CHARSET i.e. "ISO-8859-1"

Throws:

UnsupportedEncodingException - If the named charset is not supported.

IllegalArgumentException - if the string parameter is null

Since:

4.1

StringEntity

public StringEntity(String string,
 String charset)
             throws UnsupportedCharsetException

Creates a StringEntity with the specified content and charset. The MIME type defaults to "text/plain".

Parameters:

string - content to be used. Not null.

charset - character set to be used. May be null, in which case the default is HTTP.DEF_CONTENT_CHARSET is assumed

Throws:

IllegalArgumentException - if the string parameter is null

UnsupportedCharsetException - Thrown when the named charset is not available in this instance of the Java virtual machine

StringEntity

public StringEntity(String string,
 Charset charset)

Parameters:

string - content to be used. Not null.

Throws:

IllegalArgumentException - if the string parameter is null

UnsupportedEncodingException - if the default HTTP charset is not supported.

Method Details

isRepeatable

public boolean isRepeatable()

Description copied from interface: HttpEntity

Tells if the entity is capable of producing its data more than once. A repeatable entity's getContent() and writeTo(OutputStream) methods can be called more than once whereas a non-repeatable entity's can not.

Specified by:

isRepeatable in interface HttpEntity

Returns:

true if the entity is repeatable, false otherwise.

getContentLength

public long getContentLength()

Description copied from interface: HttpEntity

Tells the length of the content, if known.

Specified by:

getContentLength in interface HttpEntity

Returns:

the number of bytes of the content, or a negative number if unknown. If the content length is known but exceeds Long.MAX_VALUE, a negative number is returned.

getContent

public InputStream getContent()
                       throws IOException

Description copied from interface: HttpEntity

Returns a content stream of the entity. Repeatable entities are expected to create a new instance of InputStream for each invocation of this method and therefore can be consumed multiple times. Entities that are not repeatable are expected to return the same InputStream instance and therefore may not be consumed more than once.

IMPORTANT: Please note all entity implementations must ensure that all allocated resources are properly deallocated after the InputStream.close() method is invoked.

Specified by:

getContent in interface HttpEntity

Returns:

content stream of the entity.

Throws:

IOException - if the stream could not be created

See Also:

• HttpEntity.isRepeatable()

writeTo

public void writeTo(OutputStream outStream)
             throws IOException

Description copied from interface: HttpEntity

Writes the entity content out to the output stream.

IMPORTANT: Please note all entity implementations must ensure that all allocated resources are properly deallocated when this method returns.

Specified by:

writeTo in interface HttpEntity

Parameters:

outStream - the output stream to write entity content to

Throws:

IOException - if an I/O error occurs

isStreaming

public boolean isStreaming()

Tells that this entity is not streaming.

Specified by:

isStreaming in interface HttpEntity

Returns:

false

clone

public Object clone()
             throws CloneNotSupportedException

Overrides:

clone in class Object

Throws:

CloneNotSupportedException
