Full Changelog: v0.41.0...v0.43.0

v0.42.0

Documentation:

• Many JavaDoc additions and extensions.
• Update documentation readme to include all project javadoc links (#1022)

Enhancements

• Wrap IOException for file reads (#1021). IOException is caught and re-thrown wrapped in a runtime exception RuntimeIOException. For interactive work, this greatly reduces the number of exceptions that need to be caught. Writes will handled in the next release.
• Cleanup on aggregate function names (#1020). Abstract AggregateFunctions were given a consistent name structures. All class names now have the form: [columnType][returnType]AggregateFunction (e.g. BooleanIntAggregateFunction). If the column and return type are the same, it is not repeated (e.g. StringAggregateFunction).
• Some aggregate function classes were made public so library users can subclass
• A few methods were added to Column subclasses. Notably, an asSet() method was added to columns where it was not already present.
• improved error message for Column append methods (#1019)

v0.41.0

This is a documentation only release focused on improving JavaDoc coverage.

Documentation

The following are now fully documented for public methods.

In package tech.tablesaw.tables

• Relation

In package tech.tablesaw.api

• Table
• Row
• ColumnType

In package tech.tablesaw.columns and sub-packages

• Column
• AbstractColumn
• AbstractStringColumn
• SkipColumnType

All classes and interfaces in the following packages:

• tech.tablesaw.indexing
• tech.tablesaw.selection
• tech.tablesaw.joining
• tech.tablesaw.aggregation
• tech.tablesaw.sorting (and comparator subpackage)

v0.40.0

This release focused on minor enhancements that eliminate gaps in functionality.

Note that the change to method Table:shape() modified the String that is returned, changing the functionality of the method slightly.

Enhancements

@lwhite1
Minor extensions (#999)
Added methods:

• DoubleColumn:asDoubleArray()

• FloatColumn:asFloatArray()

• IntColumn:asIntArray()

• ShortColumn:asShortArray()

• StringFilters:isIn()

• StringFilters:iNotIn()

• IntColumn:isNotIn()

Other enhancement:

• Made Table:append() accept any Relation as its argument, not just another table.

Made Table:removeColumns() return Table rather than Relation (#1003) …

Added method Date:isNotEqualTo(LocalDate) (#1004) …

Made shape() return the name of the table, along with the shape (#1005)

Standardized names for methods, added missing methods (#1010)

• Deprecated addRow(Row) and added appendRow(Row) to make the name more consistent with append(Table).
• Added methods selectColumns() and rejectColumns() to provide variations to removeColumns() and retainColumns() that return new tables rather than modify the table in-place.
• Added method Relation:containsColumn(String name);
• other minor enhancements to code and documentation

Made Table:countBy() take varargs so the counts can group on more than one column

V0.38.5

Small release with one important bug fix. There is also a documentation enhancement.

Bug fixes

@lwhite1
SliceGroup TextColumn handling revision (#990). Fixes issue where splitting a large file on a TextColumn (as when using groups in aggregations) could cause a major increase in memory.

Enhancements

@dependabot
Bump jsoup from 1.12.1 to 1.14.2 in /html (#977)

@lwhite1
Allow TextColumn to append StringColumns, and vice-versa (#983)

@lwhite1
made all data fields protected (#991)

Documentation

@lwhite1
Update gettingstarted.md

V0.38.4

This is a relatively small release with a few nice enhancements and several bug fixes. There is also a documentation enhancement publicizing @ccleva's Parquet integration project.

Bug fixes

Fix bug where missing values in numeric columns could not be formatted. This enables arbitrary missing value indicators (e.g. "N/A") to be used in printing and saving to files.
@lwhite1

Replace parallelQuickSort with mergeSort (#968), to avoid incorrect sorting caused by race conditions when a custom sort object is used.
@lwhite1

fix issue #963 (#967) Relation.structure() fails for TableSlice with ClassCastException
@lwhite1

Enhancements

Aggregate by non-primitive column type that extends Number (#973), making it possible to add a column type for BigDecimal
@daugasauron
@Kallur

plotly - added range slider to Axis (#953) …
@smpawlowski

To support annotation in plot.ly javascript. (#944) …
@xcjusuih

Documentation

Added link to the tablesaw-parquet project in README (#966)
