Class MultiDelimiterInterpolatorFilterReader
java.lang.Object
java.io.Reader
java.io.FilterReader
org.codehaus.plexus.interpolation.multi.MultiDelimiterInterpolatorFilterReader
- All Implemented Interfaces:
Closeable
,AutoCloseable
,Readable
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.

skip
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 classFilterReader
- Parameters:
n
- The number of characters to skip- Returns:
- the number of characters actually skipped
- Throws:
IllegalArgumentException
- Ifn
is negative.IOException
- If an I/O error occurs
-
read
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 classFilterReader
- Parameters:
cbuf
- Destination buffer to write characters to. Must not benull
.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
Returns the next character in the filtered stream, replacing tokens from the original stream.- Overrides:
read
in classFilterReader
- 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
