Compilations Table

This tabbed interface shows details about the methods that were compiled during the period defined on the range navigator. The other table shows the IDs of failed compilations and a message about why they failed. Both tables show the information described in Table: Compilations Table Description.

Customizing the Table

You can customize the Hot Classes table by using the context menu to do the following:

Filtering Mechanism

You can use the filtering mechanism above the table to narrow the information shown in a table.

To filter a column:

  1. Right-click the Filter Column drop-down control to open its menu and select the column you want to filter on, for example Method.

    The column name appears in the Filter Column field.

  2. In the adjacent text box, enter the string for which you want to filter.

    Normally, to lessen the impact on performance, matching is done using only simple Kleene star wildcards. A star (*) will match zero or more occurrences of anything; for example:

    8* will match anything beginning with 8. *es will match anything ending with es.

    You can also match using regular expressions; however, resolution can take much longer with complex expressions and large amounts of data; for example:

    regexp:(YC|Young Collect).* will match anything starting with YC or Young Collect, such as YC Promotion Failed, Young Collection and Young Collector Nursery Snapshot.

    You can also build logical expressions for columns with numerical values. For instance, for a column with counts, such as the one in Memory/allocation Allocation by Class table, the expression > 100 && < 500 will filter out the classes with more than 100 but less than 500 events.

    The filter text entry field is case sensitive.
