What is component buffer and data buffer in Peoplesoft?

What is component buffer and data buffer in Peoplesoft?

Component buffer contains data of the currently active component. Data buffer contains the data of the currently active peoplesoft application it can be from a component, an application engine or application message. If the level 0 rowset is formed from a component buffer data the level 0 contains only one row of data.

What are the options to access data in the component buffer from within Peoplecode?

Access Classes The four data buffer classes are: Rowset, Row, Record, and Field. These four classes are the foundation for accessing component buffer data through the new object syntax.

What is a component buffer?

Component Buffer is the area in the memory that stores data associated with the presently active component. When a page in any component is opened, the system retrieves all of the data records for the entire component and stores them in one set of record buffers, organized by scroll level and then by page level.

What is primary record in Peoplesoft?

A primary scroll record uniquely identifies a scroll level in the context of its page: each scroll level can have only one primary scroll record, and the same primary scroll record cannot occur on more than one scroll area at the same level of the page.

How do I access component buffer in PeopleCode?

To access the same field in the component buffer, PeopleCode must:

1. Specify a scroll area and row on scroll level one: this selects a subset of dependent rows on level two.
2. Specify a scroll area and row on scroll level two.
3. Specify the recordname. fieldname on the level two row.

What are the necessary components of a buffer?

A buffer solution is made up of a weak acid and its conjugate base or a weak base and its conjugate acid. The two components maintain a pH balance that resists change when strong acids or bases are added to it.

What are the two components of a buffer system?

A buffer must contain a weak acid and its conjugate base. There are several ways a solution containing these two components can be made: Buffers can be made from weak acids or base and their salts.

What is scroll area in PeopleSoft?

PeopleSoft Application Designer automatically nests the scroll area after you set the occurs levels sequentially. Each field that you place on the page after each scroll area is automatically placed inside the scroll area preceding it until you place the next level-based control on the page.

Is NaCl and NaOH a buffer?

The mixture cannot serve as a buffer solution. NaOH is a strong base while NaCl is an ionic salt. The solution is unable to consume added hydroxide ions from a base to act as a buffer as no weak acid component is present.

What are the components of buffer?

Components of a Buffer Solution. A buffer must contain one of two choices: a weak acid and its conjugate base or a weak base and its conjugate acid. The way that the components are chosen have to do with the desired pH of the solution.

What are the compositions of buffers?

What is a buffer composed of? To effectively maintain a pH range, a buffer must consist of a weak conjugate acid-base pair, meaning either a. a weak acid and its conjugate base, or b. a weak base and its conjugate acid.

What is difference between scroll and grid in PeopleSoft?

In scroll areas, the fields appear on the page in a free form manner. In grids, fields appear as columns similar to those on a spreadsheet. Most scroll areas appear with even and odd rows in different colors.
