Closeable, AutoCloseable, Readable

public class InterpolatorFilterReaderLineEnding
extends AbstractFilterReaderLineEnding

A FilterReader implementation, that works with Interpolator interface instead of it's own interpolation implementation. This implementation is heavily based on org.codehaus.plexus.util.InterpolationFilterReader.

Since:

1.0

InterpolatorFilterReaderLineEnding

public InterpolatorFilterReaderLineEnding(Reader in,
                                          org.codehaus.plexus.interpolation.Interpolator interpolator,
                                          String beginToken,
                                          String endToken,
                                          boolean supportMultiLineFiltering)

Parameters:

in - reader to use

interpolator - interpolator instance to use

beginToken - start token to use

endToken - end token to use

supportMultiLineFiltering - If multi line filtering is allowed

Method Detail

skip

public long skip(long n)
          throws IOException

Skips characters. This method will block until some characters are available, an I/O error occurs, or the end of the stream is reached.

Overrides:

skip in class FilterReader

Parameters:

n - The number of characters to skip

Returns:

the number of characters actually skipped

Throws:

IOException - If an I/O error occurs

read

public int read(char[] cbuf,
                int off,
                int len)
         throws IOException

Reads characters into a portion of an array. This method will block until some input is available, an I/O error occurs, or the end of the stream is reached.

Overrides:

read in class FilterReader

Parameters:

cbuf - Destination buffer to write characters to. Must not be null.

off - Offset at which to start storing characters.

len - Maximum number of characters to read.

Returns:

the number of characters read, or -1 if the end of the stream has been reached

Throws:

IOException - If an I/O error occurs

read

public int read()
         throws IOException

Returns the next character in the filtered stream, replacing tokens from the original stream.

Overrides:

read in class FilterReader

Returns:

the next character in the resulting stream, or -1 if the end of the resulting stream has been reached

Throws:

IOException - if the underlying stream throws an IOException during reading

isInterpolateWithPrefixPattern

public boolean isInterpolateWithPrefixPattern()

Returns:

current state of interpolate with prefix pattern.

setInterpolateWithPrefixPattern

public void setInterpolateWithPrefixPattern(boolean interpolateWithPrefixPattern)

Parameters:

interpolateWithPrefixPattern - interpolate with prefix pattern.

getRecursionInterceptor

public org.codehaus.plexus.interpolation.RecursionInterceptor getRecursionInterceptor()

Returns:

recursionInterceptor

setRecursionInterceptor

public InterpolatorFilterReaderLineEnding setRecursionInterceptor(org.codehaus.plexus.interpolation.RecursionInterceptor theRecursionInterceptor)

Parameters:

theRecursionInterceptor - RecursionInterceptor

Returns:

InterpolatorFilterReaderLineEnding
