Constructor Detail

StreamDataSource

public StreamDataSource(java.io.InputStream iStream)
                 throws java.io.UnsupportedEncodingException

generates a new StreamDataSource with the given Stream

Parameters:

iStream - the InputStream from which the template is read.

StreamDataSource

public StreamDataSource(java.io.InputStream iStream,
                        java.lang.String encoding)
                 throws java.io.UnsupportedEncodingException

generates a new StreamDataSource with the given Stream

Parameters:

iStream - the InputStream from which the template is read.

Method Detail

getCanonicalName

public java.lang.String getCanonicalName()

returns the canonical name of the inputStream (uaaaah!)

Specified by:

getCanonicalName in interface DataSource

Specified by:

getCanonicalName in class AbstractDataSource

Returns:

always null, because stream is always to be parsed

getInputReader

public java.io.Reader getInputReader()
                              throws java.io.IOException

Gets an Reader of the File.

Specified by:

getInputReader in interface DataSource

Specified by:

getInputReader in class AbstractDataSource

Returns:

the actually set InputStream

Throws:

java.io.IOException

lastModified

public long lastModified()

Returns the time the content of this stream was last modified.

The return value is used to decide whether to reparse a Source or not. Reparsing is done if the value returned here differs from the value returned at the last processing time.

Attention: Modificationtime is only updated if a new stream is set!

Specified by:

lastModified in interface DataSource

Specified by:

lastModified in class AbstractDataSource

Returns:

long a modification time

setInputStream

public void setInputStream(java.io.InputStream iStream)
                    throws java.io.UnsupportedEncodingException

sets the InputStream and the modificationTime

Parameters:

iStream - the InputStream from which the template is read.

Throws:

java.io.UnsupportedEncodingException

setModificationTime

public void setModificationTime()

sets the modificationTime to the currentTimeMillis

setReader

public void setReader(java.io.Reader iReader)

sets the Reader and the modificationTime to the currentTimeMillis

Parameters:

iReader - the Reader from which the template is read.
