Method Detail

getCxnFormatName

String getCxnFormatName()

Format name used by MolImporter and MolExporter.

Returns:

Format name

getDescription

String getDescription()

Short human readable description.

Returns:

Short description

segments

Iterator<String> segments(Iterator<String> lines)

Enumerate multi line segments of the input structure. The returned Strings are expected to be trimmed (eg. s.trim() == s).

Parameters:

lines - Input lines

Returns:

Iterator of structures

segmentsFunction

Function<Iterator<String>,Iterator<String>> segmentsFunction()

Function to transform input lines to segments.

Returns:

Transformer function

composer

CloseableStringSink composer(Appendable target,
                             Closeable fwd)

Create composer. Composer sink concatenates trimmed String representations. For some formats (like MRV) explicit cleanup is required, thus CloseableSink.close() is required to be called.

Parameters:

target - Target to print to.

fwd - Forward closing or null

Returns:

Created composer

composer

<T extends Appendable & Closeable> CloseableStringSink composer(T target)

Convenience wrapper for composer(java.lang.Appendable, java.io.Closeable). This method typically used when a resource bound output channel is set up.

Type Parameters:

T - Closeable target type

Parameters:

target - Closeable target

Returns:

Created composer when target was present

optionalComposer

<T extends Appendable & Closeable> Optional<CloseableStringSink> optionalComposer(Optional<T> target)

Convenience wrapper for composer(java.lang.Appendable, java.io.Closeable). This method typically used when an optional output channel is set up.

Type Parameters:

T - Closeable target type

Parameters:

target - Optional closeable target

Returns:

Composer when target was present
