Method Details

readTable

public static Table readTable(@NotNull
 @NotNull String path)

Read the Deephaven format table at the specified path.

Parameters:

path - the path to the table

Returns:

the read Table

readTable

public static Table readTable(@NotNull
 @NotNull File location)

Read the Deephaven format table at the specified path.

Parameters:

location - the path to the table.

Returns:

the read Table

readTable

public static Table readTable(@NotNull
 @NotNull File location,
 @NotNull
 @NotNull TableDefinition definition)

Read the Deephaven format table at the specified path and given definition.

Parameters:

location - the path to the table.

definition - the definition for the table.

Returns:

the read Table

writeTable

public static void writeTable(@NotNull
 @NotNull Table table,
 @NotNull
 @NotNull String path)

Write the input table to the specified path in Deephaven format.

Parameters:

table - the input Table to write

path - the path to write to

writeTable

public static void writeTable(@NotNull
 @NotNull Table table,
 @NotNull
 @NotNull File path)

Write the input table to the specified path in Deephaven format.

Parameters:

table - the input Table to write

path - the path to write to

writeTable

public static void writeTable(@NotNull
 @NotNull Table table,
 @NotNull
 @NotNull TableDefinition definition,
 @NotNull
 @NotNull String path)

Write the input table to the specified path in Deephaven format. This method allows you to provide a separate TableDefinition so that users may specify different column attributes (grouping, for example) than the supplied source table may have.

The supplied definition must be compatible with the definition of the input Table.

If you do not need to adjust column attributes then use writeTable(Table, File) instead.

Parameters:

table - the input Table to write

definition - the definition to use for the table to write

path - the path to write to

writeTable

public static void writeTable(@NotNull
 @NotNull Table table,
 @NotNull
 @NotNull TableDefinition definition,
 @NotNull
 @NotNull File path)

Write the input table to the specified path in Deephaven format. This method allows you to provide a separate TableDefinition so that users may specify different column attributes (grouping, for example) than the supplied source table may have.

The supplied definition must be compatible with the definition of the input Table.

If you do not need to adjust column attributes then use writeTable(Table, File) instead.

Parameters:

table - the input Table to write

definition - the definition to use for the table to write

path - the path to write to

writeTable

public static void writeTable(@NotNull
 @NotNull Table table,
 @NotNull
 @NotNull TableDefinition definition,
 @NotNull
 @NotNull File path,
 @NotNull
 @NotNull String... groupingColumns)

The supplied definition must be compatible with the definition of the input Table.

If you do not need to adjust column attributes then use writeTable(Table, File) instead.

Parameters:

table - the input Table to write

definition - the definition to use for the table to write

path - the path to write to

groupingColumns - the columns to mark as grouping
